My iPhone 12 Pro Max hadn’t been charging on its MagSafe disc for a couple weeks. Took it into the Apple Store and the Genius realized it wasn’t charging when in its Apple made case. Was going to sell me a new case, as a faulty case is apparently not covered under AppleCare+, but for a last ditch fix reset all the system settings. And, it worked. I can now charge via MagSafe.
Weird and now I have to recover years of changed settings.
